Description
The T2720 is a professional instrument that is rugged and o-ring sealed with built-in protection for outdoor use.
The instrument is suitable for testing of single earth electrodes
such as lightning conductors and other small earthing systems. Continuity of conductors and
conduit coupling can also be measured. There is an option to make two terminal
measurements, but with reduced accuracy.
